as you may remember I cracked 2 windows this summer. both were on really dirty first cleans, where i'd been on the pane for longer than usual due to really excessive dirt.

nowadays if I think i'm going to be on a pane for longer than usual, I turn my flow right down to a trickle so i'm putting much less heat into the glass.

otherwise you could leave it up high, work first on the pane with stubborn marks for a short while, move onto other panes and then come back to the first one.

I also think that only window which are already under some sort of stress are likely to crack

[Clive McDonald]

I'd agree with that, no spacers or badly fitted spacers, a nail already causing pressure on single glazing, but..... if it cracks it's still your fault.

I don't know much about temp and tend to put my hand into the flow to get a sence of if it's too hot. I try to think of it as rubbing the window with a warm cloth and what would be okay.

But I can assure you I am not perfect or infallible.

One of the main things is not getting 'us', as hot users, a bad name. Some of the cold users would be only to happy to discredit us, so as newbies be carefull what you post on here as well.

Thats exactly my point.

I want to be completely positive, and enthusiastic about hot water, and its benefits.

If I cracked a customers window after enthusing about it, I'd feel I'd let them down.


There's one house I'm really keen to use my hot water on. Its a big house, with big panes of glass, but the have a serious insect poo problem ( they live next door to a stables, and never close there curtains at night). I would imagine I'd have the water pretty warm to soften, and remove the poo.

But I'm a little worried as to what's the highest temp I can safely, and confidently get away with.

I mean these panes as literally covered in the stuff.  I normally have to use a scourer to remove it, and even that doesn't remove all of it, and thats before I WFP

I think the point Dave made about turning the flow down to a trickle is a good idea - and the one I'd probably use.

But I'd like to know what temp most folks will , lets say, being using next week, with the temp dropping.

Thanks

What?

So if you crack panes keep it under ur hat?

You sound like Del-Boy.

[mci services]

i have asked this before but never had an answer but in cold conditions doesnt hot water freeze quicker than cold. i know it sounds daft but i remember from chemistry 20 odd years ago that hot is closer in its structure to steam and steam is closer to ice in its make up. so therefor hot freezes quicker when in enters freezing conditions

[Rob.Hall]

The answer is on another thread, it seems that you are correct in your theory.

[cat9921]

ok we can meet up monday will be on walting street most of the day

A big Thanks Alan, It was good to see for myself how it all worked and thankyou for taking the time to explain it and how it all worked. Thinking of  getting one now but have to see what the wife says 

Thanks Again

MAX 16 - 20 degs this time of year its warm enough watch out bin there and got the t shirt
that says we break windows not just clean them and what a pratt you will feel after its cost you
for replacement

[edd]

dont be a heat freak  : : : :

[Wayne Thomas]

Omnipole 6o degrees, thermalbore hose, steam coming from the glass 1st thing this morning. Should be fun tomorrow, single glazed sash windows all morning -1 .

I'll have the water flow turned right up and work very quick so glass doesn't get a chance to heat up

[NWH]

Wayne how do you feel now knowing you can go hot for about £150 lol,instead of nearly 3k with no heat adjustment.

[Wayne Thomas]

I've no regrets

[NWH]

I`m not having a dig at you as you know we spoke on the phone about it a while back now,people might be happy with the deisel heaters and i`m not knocking them good on em but i do think there a bit overpriced by quiet a bit.

[Wayne Thomas]

What's more dangerous: A gas bottle exploding or a diesel burner alight I've had to drag 5 sets of Oxy/Acetylene set ups out of a burning building and I've never been so scared in my life, someone had to do it otherwise it would have been horrendous. Been there, done it, DON'T ever want to do it again thank-you very much. I'll stick with diesel, MUCH safer even if it is more costly financially. Life is not a rehearsal.

[NWH]

Come on Wayne that sounds a bit like sour grapes lol,as someone said on here yesterday every caravan has 1 and as long as it`s connected securley and held in place jobs a good`n.

[Wayne Thomas]

If you saw the damage an exploding cylinder could do, I'm sure you'd think twice about safety versus costs.

[NWH]

Can you tell me what could happen then worst case scenario as i`ll be fitting mine next week.

[Wayne Thomas]

I really don't begrudge paying what I did for a diesel heater. Yes the gas ones are really cheap and I'm sure they are very good. Would I like to use one in a vehicle with a gas bottle? Only if there was no safer option.
I use to use a zodi hot tap heater with the gas stored outside the van while the unit was alight. I was never keen on it, but it was a means to an end.
Now I can leave my heater on whilst I'm driving if I want (safe) to pre-heat my tank if need be. I don't bother as I only use it on-demand whilst I'm cleaning the windows, cladding or whatever. I can leave it on for hours if needed whilst in use. If the unit should overheat, it will automatically cut out and there's no need for me to run back to the van and worry about the heater being damaged, just re-set the trip switches. Peace of mine.
If my heater packed up and I had to buy another heater I would still buy another diesel heater. It's a bit like the difference between an SL-2 and an extended Harris pole. Both poles will do the same job but they are so different in comparison.

[NWH]

You can only pre heat the water with your heater if you modify it and even then it would take hours and hours to heat the water up that way,that heater trips out for fun i`ve heard.If you don`t have adjustable heat IMO it`s a complete waste of time.

[Wayne Thomas]

Can you tell me what could happen then worst case scenario as i`ll be fitting mine next week.

If a cylinder was to get too hot or damaged, it's likely to ring, vibrate, ignite at the valve or turn into a flying missile, hence why they are stored in metal cages and an appropiate hazmat warning sign fitted to the vehicle transporting them so if the emergency fire appliances were called to the scene of a RTA they'd be aware of the potential fire hazzard.
